When autoinstalled APPC connections are deleted

Any autoinstalled APPC connection entry is deleted if the connection is discarded. Connection entries can also be deleted when the terminal or system logs off, or is disconnected from CICS®.

This type of implicit deletion occurs for the following types of APPC autoinstalled connection:
  • Single-session connections installed by a CINIT.

    These connections are deleted when the terminal user logs off, after the expiry of the AILDELAY system initialization value (see AILDELAY system initialization parameter).

  • Synclevel 1 connections installed by a BIND.
    Most synclevel 1-only APPC connections that are autoinstalled through a BIND request are implicitly deleted at the following times:
    • When the connection is released
    • If SNA abends
    • When CICS closes the SNA ACB
    • After the expiry of the AIRDELAY interval following a warm or emergency start (if the value of the AIRDELAY system initialization parameter is greater than zero). See AIRDELAY system initialization parameter.

    However, this does not apply to limited resource connections that are installed on a CICS generic resource member. See Synclevel 2 connections installed by a BIND.

  • Synclevel 2 connections installed by a BIND.

    Synclevel 2-capable APPC connections that are installed through a BIND request are implicitly deleted only if they are installed on a CICS generic resource member, and an affinity is ended. Otherwise, they are never implicitly deleted.

    The same applies to synclevel 1-only, limited resource connections that are installed on a CICS generic resource member.
